meeting; follow

Your computer goes to sleep mid-presentation
Many notebooks are configured to go to
sleep or shut off the screen to save energy, but this can interrupt your
presentation. To fix it, right-click an open space on the Desktop, click
Personalize, click Screen Saver, and then click the Change Power Settings
hyperlink at the bottom of the dialog box. Click the radio button adjacent to
Balanced, click Change Plan Settings, and then set the Dim The Display, Turn
Off The Display, and Put The Computer To Sleep options to Never.
Projector is “out of range”
When you see this message, it usually means
that the resolution of your source (typically a notebook or PC) device is too
high to display on the projector. Turn the projector off and turn your
attention to the PC or notebook. Right-click an empty space on the Desktop and
then click Screen Resolution. Click the Resolution drop-down, and drag the
slider to match the projector’s native resolution. Click Apply and OK to close
the dialog box.
Image fails to appear on the projector
Make sure the requisite cables are
connected, the PC or notebook and projector are powered on, and that the
projector has had sufficient time to warm up. Set the projector to the proper
source by pressing the Source or Input button. Another possible way to pinpoint
the problem is to right-click an empty space on the Desktop and then click
Screen Resolution. Next, click the Connect To A Projector hyperlink. Your
options are Disconnect Projector, Duplicate, Extend, and Projector Only. Click
one of the latter three to enable the image on the Projector.

Prevention
The best way to avoid problems is to
perform regular maintenance on your projector. Be sure operate your projector
within the minimum and maximum temperature and humidity ranges. Excesses can
reduce the lifespan of the projector lamp, leading to overheating. Run the
projector at less than its peak brightness to extend the lamp life. If your
projector supports it, use Eco Mode. Avoid unplugging the projector immediately
after the presentation, to give the fan long enough to cool the lamp down.
